Now, Duffy and McFadden perform as two lead vocalists, typically backed by a live band, sharing verses and choruses throughout the show.
They said nerves still creep in at the start of a tour, but it’s more excitement than fear, particularly when performing new material.
“We get excited for getting out and doing it live. I don’t think I could do this job if we didn’t have the live shows that we do,” McFadden said.
They will entertain Belfast audiences in April – and both performers singled out Belfast’s fans as among the most energetic they play to.
“You give your best show when the audience give you that kind of energy. So we love coming and playing up here,” Duffy said.
They kicked off their 2025 tour in Belfast and said the crowd “raised the roof off the place”.
“They didn’t even want us to sing. They sang every song themselves,” Duffy said.
“We were trying to sing, but there was no point. We just put the mics out and they’d just take over.”
